Kim HyoYeon, a girl who just wants to live her life freely. An amazing dancer, an art major and a dreamer. Living her life freely, with no one there to control it is what keeps HyoYeon going, it's what thrives her. No boys, no parents, no one to hold her down.  But what would happen if suddenly someone held her down, without even realizing it?  What if HyoYeon fell so deeply in love? Would she keep going? Would she want to keep going? What if that lover.... Left her.

HyoYeon. Kim Hyoyeon is just an ordinary girl, training to become an idol, living a life in 21st century South Korea. But that life is turned upside down when a strange man calling himself The Doctor pulls her into a tiny box.... ''It's bigger on the inside'' she whispered under her breath.
